    vcl: refresh font cache only on real change
    
    GTK3 emits way too many style-updated, which triggers font cache updates. The
    avoidance of unecessary font cache updates was first implemented in 29c55564.
    Unfortuantely, it seems that the current font-options was never set as
    last-seen font-options, so still to many fonts-changed were emitted
